Lux describes the perceived illumination of known space.

Lumen measures how much visible light is produced by an object.

follow the following steps-

Enter illuminance in lux.

Enter unit of area as either ft^{2} or m^{2}

Enter radius of the spherical light source, or you may enter directly the surface area.

Click on Calculate button, and you will get the result in lumens.

Following formula converts lux into lumens.

**ΦV(lm) = 0.09290304 × Ev(lx) × A(ft2)**

Where,

ΦV(lm) = Luminous flux in lumens

Ev(lx) = Illuminance in lux

A(ft2) = Spherical surface area

0.09290304 is a constant value

**Lux to a lumen conversion table**
